any hints on that?

From what I remember, the A* VIs can be used with either an occupancy grid or a directed graph.  The costs on an occupancy grid are simply the distances between neighboring nodes, so it only allows you to find the shortest path.  If you use a directed graph as the map, you can have more control by specifying multidimensional coordinates for each node.  This is still a "shortest path" calculation, but you may be able to manipulate the coordinates to reflect other parameters.
